Prawns are omnivorous, and in the wild they eat a variety of food, including plankton, carrion and other microorganisms. Their diet also consists of detritus, or fragments of decaying organic matter, small shellfish and worms.Continue Reading
Prawns are crustaceans and have a diet similar to that of other crustaceans. Newly born prawns eat modestly and often feed on plankton that live near the surface of the water. They also eat small marine plants and can eat seaweed, as long as it's small enough for them to eat. Prawns grow quickly after their first year, and this is when they can swim to search for a variety of food. As natural scavengers, they aren't picky eaters and consume almost anything that's small enough to eat, including mud, sand, dead fish and crabs. Prawns are among the rare type of animals that prey on their own kind to survive, especially if there's a scarcity of food in their natural habitat.
King prawns are sensitive to light and only hunt at night. Tiger prawns are active day and night. Both prawns are highly popular as a seafood delicacy and are often farmed in ponds near the sea. Cold-water prawns are deepwater crustaceans and don't eat mud and sand, which is why they have clearer veins than the warm-water king and tiger prawns.Learn more about Marine Life
Most animal plankton (zooplankton) and plant plankton (phytoplankton) live several months, but some species may live for more than a year. However, there are thousands of species of plankton, making it impossible to pinpoint a specific average life span that can apply to all plankton species.Full Answer >
Mussels are filter feeders that filter microscopic aquatic life, such as plankton, from the water around them. The larvae of some mussel species are temporarily parasitic.Full Answer >
Sea horses are carnivores and primarily eat small crustaceans and plankton. They are best known for being the only member of the animal kingdom where the males give birth to the babies. However, they also have an unusual digestive system because they do not have stomachs or teeth.Full Answer >
